Preheat oven to 350°F (175°C) and lightly grease a 9-inch round baking dish or pie plate.
In a high-speed blender, combine the cottage cheese, eggs, maple syrup, and vanilla extract. Blend until the mixture is completely smooth and no lumps remain.
In a medium mixing bowl, whisk together the almond flour, all-purpose flour, baking powder, sea salt, and lemon zest.
Pour the wet blender mixture into the dry ingredients and whisk until a smooth batter forms.
Distribute the fresh berries evenly across the bottom of the prepared baking dish.
Carefully pour the batter over the berries, ensuring they are evenly covered.
Bake for 35 to 40 minutes, or until the center is set and the edges are lightly golden brown.
Remove from the oven and allow to cool for at least 10 minutes to let the custard set before slicing.
Serve warm or chilled.
